Fixed-Wing UAV Design Engineer – Airframe & Mechanical Systems
? [Thanjavur, Tamil Nadu] | Full time

We are looking for an experienced Fixed-Wing UAV Design Engineer to design and develop lightweight, robust, and production-ready UAV airframes and mechanical systems.
The role will focus on composite airframe design, mould/tooling design, critical mechanical interfaces, modular airframe architecture, and payload integration, working closely with Aerodynamics, Composites, Avionics, Manufacturing, and Flight Test teams.

Key Responsibilities
• Design and develop fixed-wing UAV airframes, including fuselage, wings, empennage, control surfaces, hatches, and internal structures.
• Design composite structures using CFRP/GFRP, sandwich panels, foam/honeycomb cores, and bonded assemblies.
• Optimise airframes for weight, strength, stiffness, aerodynamic requirements, manufacturability, and serviceability.
• Design composite moulds, master patterns, assembly fixtures, bonding fixtures, and manufacturing tooling.
• Develop critical mechanical interfaces such as wing-fuselage joints,



quick-release mechanisms, locking systems, hinges, control linkages, landing interfaces, and structural connectors.
• Design modular airframe architectures for rapid assembly, transportation, maintenance, and field replacement.
• Develop mechanical integration solutions for modular payloads, EO/IR systems, sensors, antennas, avionics, batteries, and mission equipment.
• Ensure payload integration considers CG, structural loads, vibration isolation, accessibility, thermal requirements, and cable routing.
• Perform GD&T;, tolerance stack-up, structural calculations, mass/CG analysis, and design reviews.
• Work closely with the Composite Fabrication Team to take designs from CAD → mould/tooling → prototype → assembly → flight testing → production.
• Support prototype builds, ground testing, flight testing, failure analysis, and iterative design improvements.
• Prepare complete 3D CAD, manufacturing dr
